Crowds reportedly stormed the QuickTrip on West Florissant, causing a lot of damage. A window was also smashed out of a News 4 live truck.

Two groups of protesters gathered around 8:00 Sunday night in Ferguson to bring awareness to the death of Michael Brown, 18, who was shot and killed by police Saturday.

At least fifteen area police agencies have been called Ferguson. Police set up a staging area at West Florissant and Ferguson Road. Police are also staging at the Plaza at the Boulevard parking lot, where officers are seen putting on riot gear. Dozens of police vehicles are on scene, from all over St. Louis County, including Chesterfield, Country Club Hills and the Missouri Highway Patrol.

Following the shooting "hundreds of angry residents...[came] out their apartments" shouting "kill the police."

According to the AP, a St. Louis County Police Department spokesman said "a Ferguson officer shot the man," but he "[did not] give a reason for the shooting." The residents confronted police "for several hours" thereafter.

The "St. Louis chapter of the NAACP called for the FBI to look into the" shooting. NAACP member John Gaskin said FBI involvement could "protect the integrity of the investigation."

He added:

With the recent events of a young man killed by the police in New York City and with Trayvon Martin and with all the other African-American young men that have been killed by police officers--this is a dire concern to the NAACP, especially to our local chapter.

The officer who shot Brown has been placed on "administrative leave" while Ferguson police investigate the shooting.

St. Petersburg, Florida - Michael Brown's family has hired the same Florida civil rights attorney who currently represents Trayvon Martin's family.

Brown,18, died Saturday after being shot multiple times by a suburban St. Louis police officer. St. Louis County Police Chief Jon Belmar says it all began when Brown physically assaulted the police officer, pushing him into the officer's vehicle. He said there was a struggle inside the car, and at some point Brown reached for the officer's weapon. One shot was fired inside the vehicle.

Brown suffered fatal gunshot wounds outside of the vehicle, approximately 35 feet from the car. Belmar said multiple shell casings were found at the scene, and that Brown was shot more than once, but an exact number of shots fired has not yet been determined. All the shell casings came from the officer's weapon.

Belmar confirmed Brown was unarmed at the time of the shooting. He did not say what led to the struggle inside the officer's car.

Brown's mother, Lesley McSpadden, said Sunday she doesn't understand why police didn't subdue her son with a club or Taser. She said police have not explained why the officer confronted him.

"I would like to see him fired," McSpadden said. "I would like to see him go to jail with the death penalty."

"My son just turned 18 and graduated from high school, and he don't bother nobody," she said Saturday night. She said he was looking forward to starting at Vatterott College next week.

"They told me how many times my son was shot. Eight," McSpadden said.

She said he was visiting his grandmother, who lives in the complex, and was returning from the store.

The St. Louis County NAACP has called for an FBI investigation and Belmar has contacted the FBI.

Meanwhile Tallahassee civil rights attorney Benjamin Crump and Brown's family are set to take part in a news conference Monday afternoon at a church in Jennings, Missouri where Crump will address the media.

Crump continues to represent Trayvon Martin's parents after their unarmed 17-year-old son was fatally shot on February 26th, 2012 as he walked from a convenience store to his father's Sanford condo during a visit from Miami.

Martin's parents accused Sanford police of botching the investigation and criticized them for not arresting 28-year-old George Zimmerman, who says he shot Trayvon Martin in self-defense.

Zimmerman was eventually arrested and went to trial but was found not guilty of second-degree murder and manslaughter in July of 2013.

The FBI is "reviewing" the shooting death of an unarmed teenager by a police officer, federal authorities said today.

Michael Brown, 18, was shot multiple times and killed him during a confrontation with a Ferguson, Missouri, cop on Saturday afternoon, according to authorities.

Looting, Vandalism After Vigil for Missouri Man Killed by Cop

Brown was not carrying a weapon and, according to one witness, was facing the officer with his hands raised in the air when the officer shot him, Piaget Crenshaw told ABC News.

The officer has not been identified and has been placed on administrative leave by the Ferguson police department. The St. Louis County police department is the lead agency on the shooting. The FBI is "reviewing the matter," an FBI spokesman told ABC News.

The struggle began when the officer encountered two men, one of whom was Brown, in the street outside of an apartment complex, and one of the men pushed the office back toward his squad car, according to police. A shot was fired inside the squad car and then multiple shots were fired at Brown outside the car, killing him, authorities said.

Brown's death sparked outrage in the community and prompted residents to march to the police station, demanding answers before holding a candlelight vigil Sunday night.

The vigil erupted into violence, with some individuals breaking into stores and looting goods while others vandalized police vehicles. A fire broke out in a QuickTrip store that had been looted earlier.
